The Matlab "trick" for this is to rely on memory storage order...
x=mean(reshape(x,60,[])).';
leaves column vector of the averages of the 60-element columns created by the reshape operation. If you number of elements isn't precisely divisible by 60, you'll need to account for it in the second argument when reshape to the multiple or truncate first.
